Application filed February 3, 1921.

To all whom it may concern.-

Be it known that 1, WILLIAM LEON, a citizen of the United States,residing at Niagara Falls, in the county of Niagara and State of NewYork, have invented certain new and useful Improvements in KeylessLocks, of which the following is a specification.

My invention relates to keyiess lock, and more particularly to locks fordoors trunks, chests, etc.

One of the objects of my invention is to provide a lock which can beeasily and conveniently manipulated without the use of a key and whereinprovision is made for actuating the same from either side of a door.

Another object of my invention is the provision of a keyless lock ofthis type which embodies a principle permitting the use of permutationmechanism comprising a single series of tumblers or a plurality ofseries and in which provision is also made for readily changing theconcerted order of the tumblers so that a diiferent adjustment ormanipulation of one or more of the tumblers of the series, or each ofthe series will be required to operate the look.

A. further object of my invention is the provision of a simple,inexpensive and durable device of this kind which is selfcontained andreadily insertable or removable from a door or other object and in whichthe principle involved can be readily embodied in various modifications.

With these and other objects inaview to appear hereinafter. theinvention consists in the novel features of construction, and in thearrangement and combination of parts to be hereinafter described andmore particularly pointed out in the subjoined claim.

In the drawings Fig. 1 is a perspective view of a portion of a doorshowing one form of my invention applied thereto.

2 is a vertical section through the door and co-operating door jambshowing my improved keyless lock in sectional elevation.

Reference being had to the drawings in detail, like numerals refer tolike parts throughout the several figures. 7

The numeral .11 designates a door. 12 a door jamb having abolt-receiving pocket 13 and a bolt or latch plate 141- secured thereto.said bolt or latch plate being provided with the usual opening whichregisters with the pocket 13 so as to allow the belt of the lock to passthrough said opening and enter said pocket. The door is mortiscd fromits edge, as at 15. and one or both sides thereof, as may be desired. itis provided with an opening or openings 1.6 formed through one or bothside walls of the mortise 15.

"in the drawings 1 have shown a lock which can be manipulated from bothsides of the door and consequently both side walls of the mortise areprovided with the openings 16 but it will be apparent that in a lockadapted to be manipulated from one side of the door only, the opening 16is formed in one side wall only of said mortise.

The lock comprises a lock plate 1 which is secured to the edge of thedoor in a manner to close the front end of the mortise 15, and thisplate is provided with a bolt opening 18 and with two inwardlvprojectingsleevelike members 19 provided with transverse slots 20 alongdiametrically opposite lines, the slots being arranged in twolongitudinal series with the slots of one series registering with thoseof the other.

21 designates a frame which s preferably L-shaped with one arm 22thereof disposed horizontally and preferably in slidable contact withthe upper wall of the mortise and horizontal section 2, the door ami)section similar to its other arm 23 disposed vertically. Said frame hasa lock-bolt 24: secured thereto which extends outwardly therefrom andthe outer end of which is guided for movement in the bolt opening l3 ofthe lock plate 17.

Detachably secured to the vertical arm of the said lock frame are twosupporting spindles or rods 25, each of which is entered in one of thesleeve members 19, and each having a series of pins 26 extendingtherethrough and projecting therefrom at diametrically opposite points.The opposite ends of said pins extend through the slots 20 at oppositesides of the sleeves 19 and proj ect a distance outwardly beyond thesurface of said sleeves. The supporting spindles or rods 25 arepreferably reduced at their inner ends to provide a shoulder which bearsagainst the vertical arm of the lock frame, the reduced portion thereofextending through said arm and having a retainer pin 27 passedtherethrough so as to securely hold said spindle on said frame andprevent longitudinal movement thereof.

The lock plate 17 and vertical arm 23 of the frame 21 may, in a broadsense, be termed supporting elements or members since they support thesleeve-like members 19 and the supporting spindles or rods 25, and saidsleeve-like members and supporting spindles or rods may be termedtelescopic rods, since said spindles or rods are adapted to slide withsaid sleevelike members.

In the drawings I have shown four pairs of slots 20 in each sleeve-likmember 19, each pair being comprised of opposite registering slots, andfour pins 26 in each supporting spindle or rod 25, but these may bediminished or increased in number, as may be desired.

Surrounding each sleeve-like or outer rod member 19 are four innertumbler members 28, each of which is provided with a bor 29 of a size topermit free rotation of said outer rod member, each tumbler member beingcounterbored, as at 30, to form an annular pin-way or groove and fromsaid in-way or groove a longitudinal groove 31 extends, which at timeswill receive the projecting ends of the pins 26, as will be hereinafterdescribed. By counterboring the inner tumbler member, forwardly-itaei11gshoulders 32 are formed therein.

Each of the inner tumbler members is also provided with an externallongitudinal projection or rig 33 serving as a key, and being preferablyl-shaped. Surrounding each of the inner tumbler members 28 an outertumbler member 34, which is provided with a circular series of internallongitudinal V- shaped notches 35 serving as key ways. On the outerperiphery of said. outer tumbler member a circular series of letters,figures, or other characters 36 are formed, one letter or othercharacter being provided for each in the outer tumbler member.

In the preferred form, the diameter of the outer tumbler is somewhatgreater than the thickness of the door so that with the lock positionedcentrally in the door, or more particularly, with the telescopic rodspositioned centrally within the mortise ot the door, the outer tumblermembers project beyond opposite faces of the door.

The openings 16 formed in the door are closed by plates 37, which may befastened to the door in any suitable manner, preterably so that theouter plate can be removed only when or after removing the inner plate,as and in the manner commonly provided for in the better class ofout-door locks of usual construction now commonly employed.

Each plate 37 has two slots 38 formed therein. through which the outertumbler members 3i can be manipulated, each plate having indicating orguise marks 39 with which predetermined characters on the outer tumblermembers are adapted to be alined so as to position the lock mechanism topermit opening or the door. The lock bolt 2% is provided with alongitudinal opening 40, one longitudinal wall of which is provided witha series of gear teeth ll. Passing through the door and the plates 37and projecting outwardly a distance from both plates is an operatingspindle d2 having knobs 43 secured to opposite ends. Ata pointmidlength, this spindle is provided peripherally with teeth 4.4K whichare .in mesh with the gear teeth l1 in the slot 40 and by means of whichthe lock trame and the inner members o1"- the telescopic ends securedthereto can he moved outwardly and inwardly.

With the parts in the position shown in Fig. 2; the lock oolt 24-,projected outwardly through the opening 18 in the lock plate i7 andextends into the pocket lI-lin the door jamlnthe tumblers being poshtioned to prevent rot tion of the operating spindle 4-2. l l ith thetumblers so positioned, the inner members are moved iorwardly in theouter members ii) of the telescopic rods with the pins 26 of s; 'd innermembers engaging the front ends of the slots 2(), said pins projectinginto the annular grooves or key ways 30, as clearly shown in Fig. 6.With the projecting ends of each pin thus arranged the inner members ofthe telescopic rods are held against forward movement by the inner endof the tumbler memberdirectly in advance and against rearward movementby the shoulder of the inner tumbler member with which it dircetlycoacts.

With the pins rojecting within the pin ways 30 of the several tumblers,said tumblers are free to be rotated, but before it is possible towithdraw the lock latch 2% from the pocket 13 in the door jamb, it willbe necessary that the longitudinal grooves 31 in the inner tumblermembers be brought into alinement with the projecting ends of the pins26, and to accomplish this, the operator must know the exact characterof each tumbler which must be brought into alinement with the indicatingor guide marks 39 on the outer or inner plate 37. When the tumblers arerotated so that all longitudinal grooves 31 therein are alined with thepins 26, the knobs 43 are free to rotate, and upon rotating said knobs,the operating spindle 42 to which they are secured will cause the lockbolt to be moved inwardly, which bolt being secured to the frame 21 willcause the inner members of the telescopic rods to move inwardly and thepins to enter the longitudinal grooves '31 in the inner tumbler members,as clearly shown in Fig. 7. With the parts in the positions lastdescribed, rotation of the tumbl r members is prevented, and the door isfree to be opened or closed.

It is, of course, to be understood that any suitable spring or othercatch device may be used in connection with this improved loclr. eitheras a separate unit, or as a part of this locking mechanism. It is alsoapparent that this locking mechanism can be arranged so that thetumblers are accessible from one side of the door only, and that anycatch device employed can be ogerated from both sides of the door, sothat the door may be held closed, although not locked. More over, in theevent of the tumblers being accessible from one side of the door only, akey lock may be employed at the other side of the door in addition tothis improved lockingmechanism.

Vl henever it is desired to change the combination, it is simplynecessary to remove one or more of the outer tumbler members and placethe key of the co-acting inner tumbler it would be possible tomanipulate the locking mechanism. Therefore, the combination of oneseries of tumblers could be changed and the combination of letters onthe other series of tumblers left intact; or if desired, both series canbe changed so that if a combecomes known to others, it will be found asimple matter to change the combination to any degree desired, even toinclude an entirely new set of letters or characters.

ln 10, 45 designates a trunkor chest having cover 16, the cover beingmortised, as at 15 and having a frame 21 provided with a slide bolt 2%at the inner end of the frame. In this modification the lock plate 17 isprovided with an inwardly extending arm l7 to which the outer member 19'of the telescopic rod is secured. To the frame, above the slide bolt 2%,the inner member 25 of said rod is secured, and surrounding said outermember are shown tumbler members 33 of the permutation mechanism. Thismechanism, which includes outer and inner tumbler members and the outerand inner members 19 and 25, respectively, of the telescopic rod, isidentical with the permutation mechanism illustrated in the precedingfigures of the drawings.

The trunk or chest to is provided with a pocket 13, and closing saidpocket is a latch plate 14: having one or more openings 48. The lockbolt 24: is provided at its lower edge with one or more hookshapedprojections 49, which are adapted to pass through the openings 18 in thelock plate 17 and through the openin s 48 in the latch plate, whichlatter openings register with the openings 18 in said lock plate. Whenthe frame 21 is moved to the right hand end of the mortise 15, as shownin Fig. 10, the tumblers and projecting ends of the pins of thepermutation mechanism will be in positions corresponding to those shownin Fig. 6, so that the toothed portion of the spindle e1 cannot berotated to actuate the slide bolt 24. It is, of course, to be understoodthat the tumblers will be accessible from the exterior of the cover in amanner similar to that shown in Fig. l, and that when manipulating thetumblers and the proper combination of characters thereon are broughtinto concert and in line with some indicating or guide marl; on thecover 46, the lock can be actuated, or in other words, moved toward theleft, and when so moved the hook ends of the projections 49 can bewithdrawn through the openings 48 in the latch plate. 14.

The sleeve-like outer member of each telescoping-rod may also beconsider d as a housing for a portion of the inner member, or thesupporting spindle or rod 25, as more specifically termed.

Having thus described my invention, what I claim is The combination witha door having a mortise therein, of a keyless lock entered in saidmortise and comprising a lock plate closing the outer end of saidmortise, a supporting member spaced from said lock plate, a telescopicrod connecting said supporting bination which is being used to open thedoor member with said lock plate and comprising an outer sleeve-likemember having a plurality of longitudinally disposed slots therein andan inner member having pins projetcing therefrom and extending outwardlythrough said slots, a lock bolt on said supporting member guided in saidlock plate and having a longitudinal slot therein provided with gearteeth in one of its Walls, and

tumblers surrounding said sleeve-like outer 10 member, each tumblerhavlng an mternal annular groove and a longitudinal groove opening intosaid annular groove, said pins projecting into said annular groove whensaid lock bolt is in looking position and into said longitudinal grooveswhen said look bolt is in unlocked" position, and a spindle providedoircumferentially with teeth meshing with the teeth in said slot.

In testimony whereof I affix my signature.

WILLIAM LEON.
